The canonical Shelby Mustang — from the 1965 SCCA B-Production R-model to the Ford-built cars of 1969–70.
The GT350 is the car that started Shelby American's Mustang programme. The 1965 cars were built at Shelby's Los Angeles airport shop from Wimbledon White fastback Mustangs stripped and re-engineered as pure road-race weapons — Cobra 289 Hi-Po V8, side-exit exhausts, override traction bars, fibreglass bonnet with functional scoop, plexiglass rear quarter windows and a relocated battery. Thirty-four R-models were built to SCCA B-Production specification and dominated the class, taking the 1965 championship.
1966 broadened the appeal — five colour options, an optional Paxton supercharger, and Hertz Rent-A-Racer 'GT350H' cars that put Shelby ownership within reach for a weekend. Production moved to A.O. Smith in Michigan for 1967–68, and to Ford's own Kar Kraft in Dearborn for 1969–70, with each year producing a visibly and mechanically different car.
The GT350 established the Shelby Mustang idiom, took an SCCA national championship in its first season, and remains the most historically important American production race-and-road car of the 1960s.
| Variant | Years | Production | Notes |
|---|---|---|---|
| GT350 (1965 street) | 1965 | 526 | Wimbledon White fastback only; K-code 289 Hi-Po, side-exit exhaust, override traction bars, plexiglass rear windows. |
| GT350 R (1965 competition) | 1965 | 34 | SCCA B-Production race cars built at Shelby American; won the 1965 B-Production championship. Two prototypes counted separately. |
| GT350 (1966 street) | 1966 | 1,373 | Five colour options; optional Paxton supercharger; steel side windows replace plexiglass mid-year. |
| GT350H (1966 Hertz) | 1966 | 1,001 | Rent-A-Racer cars for Hertz; predominantly black with gold stripes. |
| GT350 Convertible (1966) | 1966 | 4 | Four one-off cars gifted by Carroll Shelby; not offered publicly. |
| GT350 (1967) | 1967 | 1,175 | New longer Mustang body; last small-block-only year. |
| Cobra GT350 (1968) | 1968 | 1,457 | 1,053 fastback + 404 convertible. 302 V8 — 250 bhp standard or 335 bhp with the factory Paxton supercharger option. 'Cobra' branding across the Shelby range. |
| GT350 (1969) | 1969 | 960 | 821 fastback + 139 convertible. Ford-built at Kar Kraft; 351 Windsor V8; five-vent fibreglass bonnet shared with the GT500. |
| GT350 (1970) | 1970 | 318 | Unsold 1969 cars re-VIN'd under FBI supervision and sold as 1970 models — not new production. Black chin spoiler and twin bonnet stripes distinguish them. |
Start with identity, paperwork and originality. For the Shelby GT350, the strongest cars have continuous ownership history, matching numbers where applicable, factory build documentation and Shelby American Automobile Club (SAAC) registry entries. 1965 R-model status, SAAC registry entry, matching-numbers K-code engine, original colour, and continuous documented ownership are the primary drivers. Hertz GT350H provenance carries a distinct premium.
The 289 Hi-Po K-code V8 (1965–67) is the definitive Shelby engine and needs specialist top-end and valvetrain expertise. 1968 introduced the 302, and 1969–70 cars use the Ford 351 Windsor. Confirm K-code stamping, correct high-riser intake and factory Tri-Y exhaust manifolds on the small-block cars. A proper pre-purchase inspection includes cold-start behaviour, compression and leak-down testing, underbody photography, chassis inspection for repair and correction, and a long road test to expose heat-related faults. Deferred maintenance on a Shelby is almost always more expensive than paying up for a better-sorted example.
Shelby cars carry a large proportion of hand-finished, low-volume bodywork — fibreglass panels on the Mustang-based cars, hand-formed aluminium on the Daytona Coupe, and composite panels on the Series 1. Use a paint-depth gauge, lift access and a specialist familiar with the model's factory panel gaps. Value is dramatically affected by structural repairs, refinished panels and missing original trim. Documented cosmetic refresh is acceptable; concealed accident or fire damage must be priced severely.
1965 cars — particularly the 34 R-models and the earliest street cars — are the market and historical top; 1966 cars (especially the black GT350H Hertz cars) are the recognisable icons; 1967 is the last small-block-only year; 1968–70 broadens into Cobra GT350 and Ford-built cars. Specification, colour, options and limited-build variants move values significantly. Buy the best-documented example in the most desirable specification you can justify, not a tired example of a rarer derivative that will need years of corrective work.

1965 R-models sit in a market of their own — chassis-by-chassis, seven-figure trades against documented period race history. 1965 street cars and Hertz GT350Hs form the recognised collector tier and remain firm. 1967 is the last small-block year and well supported; the 1968 Cobra GT350 and Ford-built 1969–70 cars are the accessible entry to Shelby ownership and trade steadily rather than appreciating.
| Date | Auction | Car | Mileage | Result |
|---|---|---|---|---|
| 2024-08-16 | Mecum Monterey | 1965 GT350 (SFM5S099) | — | $412,500 Sold |

The 1965 R-model and documented 1965 street cars are as firm as any American collector car of the era. 1966 GT350 and Hertz H-cars are recognised, tradable and liquid. Later cars are stable rather than appreciating; the marque premium sits squarely on the 1965–66 Shelby American–built cars.
